Epilepsy – Affect Type & Disorder

Epilepsy – Affect Type & Disorder

Epilepsy is a neurological disorder that could lead to uncontrolled bursts of electrical activities owing to the improper functioning of nerve cells. This temporary uncontrolled burst or excessive surge of electrical activity within the brain is called a Seizure, which could give rise to symptoms depending on which part of the brain is affected. 

 

Epilepsy is a chronic disease that causes repeated seizures, usually when someone experiences 2 or more unprovoked seizures within 24 hours.  twenty-four hours apart. “Unprovoked” seizures are those that aren't brought on by a usual cause, like alcohol withdrawal, heart issues, or hypoglycemia, that is once someone has extraordinarily low glucose levels.

 

Seizures are also the results of change in normal biology or a brain injury, however, typically their cause is unknown. The words “seizure disorder” and “epilepsy” are typically used interchangeably.

 

Types of seizure -

There are 2 main sorts of seizures—Focal, which are referred to as partial seizures, and generalized.

 

Focal seizures begin with abnormal discharge restricted to at least one tiny region of the brain. Affects one area of the brain and stays confined to 1 hemisphere. Symptoms will embody altered behaviors, thoughts, or movements.


Causes:

o   Focal seizures are also caused by an associated underlying structural abnormality within the brain.

o   Focal seizures may result to go trauma, stroke, infection, tumors, or different causes.

o   Certain genetic disorders may cause focal seizures.

Types of Focal Seizures

Focal seizures are of 2 types

1.    Simple focal seizures or Focal aware seizures: When a person is conscious and fully aware of what is happening

2.    Complex Focal seizures or Focal impaired-awareness seizure: Consciousness is usually affected and awareness is disrupted, and you will not be aware of what is happening around you.

 

 

Generalized seizures begin with a widespread, excessive discharge involving each hemisphere, or side, of the brain. Symptoms embody staring and blinking, jerking movements, loss of tone, and stiffening of limbs. once the whole brain is involved, symptoms include regular, full-body jerking. Seizures that arise from each hemisphere of the brain at the same time and spreads over

 

The reason for generalized seizures is likely to be genetic. Very seldom is the disorder inherited disorder and typically it's an unknown cause.

 

Difference Between Epilepsy and Seizure -

Understanding the distinction between seizures and brain disorder starts with knowing seizures constitute 2 main classes counting on why they happen.

 

o   Provoked seizures: These happen attributable to different conditions or circumstances (high fevers, alcohol or ending, low blood sugar). These seizures constitute 25% to 50% of all seizures.

o   Unprovoked seizures: These are not symptoms of a current medical condition or circumstance and occur once a person’s brain will cause spontaneous seizures. This conjointly includes seizures that happen after 7 days when a particular cause (like a head injury or stroke) had occurred.

Epilepsy could be a brain condition that puts you in danger of getting spontaneous, unprovoked seizures. Health care suppliers diagnose it after you have a minimum of 2 unprovoked seizures, Or you have one unprovoked seizure and have a high risk of getting a minimum of a new one within the next ten years. Having one unprovoked seizure will increase the chances of getting another.

 

How does it affect our body?

Your brain contains billions of cells called neurons. These cells transmit and relay chemical and electrical signals. One nerve cell in your brain connects to thousands of additional, forming human neural activity networks. Those networks of your brain work along so that you'll be able to do things like solve issues, store recollections and move around.

 

Seizures happen once a malfunction causes neurons to fire electrical signals uncontrollably. That causes neurons to go haywire. The more haywire neurons, the larger the impact of the seizure. If these malfunctions happen more often, it will affect how your brain cells work and cause seizures to happen.

 

If they keep happening or seizures last too long, these electrical malfunctions can harm and destroy your brain cells. once this happens to enough neurons in a part of your brain, the result may be permanent brain damage. Seizures may cause severe changes in your blood chemistry as your body tries to manage the physical effects of convulsions.

 

Causes of Seizure -

 

Seizures will happen for several different reasons. These include:

 

o   Aneurysms.

o   Brain tumors

o   Cerebral hypoxia (lack of oxygen).

o   Severe concussion and traumatic brain injury.

o   Degenerative brain disorders like Alzheimer’s disease

o   Drugs and alcohol (this includes prescription medications, recreational medicine, and even caffeine).

o   Drug or alcohol withdrawal.

o   Eclampsia

o   Electrolyte issues, particularly low sodium (hyponatremia).

o   Fevers, particularly high ones

o   Genetic disorders (conditions you've got at birth that you just transmissible from one or both parents).

All you need to know about Syphilis
All you need to know about Syphilis
ETIOLOGY: Syphilis is caused by T. pallidum.INCIDENCE: Each year, there are 29,000 new cases of syphilis. This figure represents probably only 10% of actual cases.CLINICAL FEATURES1. Primary syphilis: After an average incubation period of approximately 3 weeks, a smooth, painless ulcer called a chancre appears at the site of primary inoculation. The chancre heals without treatment in approximately 3 to 6 weeks; at about the same time, a painless uni- or bilateral regional adenopathy develops.2. Secondary syphilis represents disseminated disease and occurs in all patients with untreated primary infection. The lesions of secondary syphilis are papulosquamous lesions that occur over the entire trunk, extremities, penis, and buttocks. Fever and weight loss occur in 70% of patients.3. Tertiary syphilis occurs at least 10 years after the primary infection in at least 30% to 35% of untreated patients. The two most important manifestations of tertiary syphilis are cardiovascular syphilis, causing thoracic aneurysms, and neurosyphilis, causing meningitis, stroke, seizures, dementia, general weakness, and posterior column dysfunction.DIFFERENTIAL DIAGNOSES— Chancroid— HSV type 1 infection— Lymphogranuloma venereum— Tinea, sarcoid— Lichen planus— Seborrhea dermatitis— Molluscum contagiosum— Traumatic ulcer— Furuncle— CarcinomaEVALUATION: The clinical diagnosis can be confirmed by darkfield microscopic examination or more commonly serologic testing.THERAPY1. The standard treatment for primary, secondary, and early tertiary syphilis is benzathine penicillin G (2.4 million U administered intramuscularly as a single dose).2. For late tertiary syphilis or neurosyphilis, benzathine penicillin G (2.4 million U, three doses administered intramuscularly 1 week apart) is used. Doxycycline (100 mg orally twice daily for 14 days) can be given to patients who are allergic to penicillin.DISPOSITION1. Primary and secondary syphilis can be treated on an outpatient basis.2. Patients with neurosyphilis or major cardiovascular manifestations require admission for intravenous therapy.

What is Pemphigus Vulgaris?
What is Pemphigus Vulgaris?
Pemphigus Vulgaris is a rare disease that affects elderly patients. The mortality rate is 10%; most deaths result from steroid complications, secondary infection, dehydration, or thromboembolism. Pemphigus Vulgaris is caused by the attachment of immunoglobulin G autoantibodies to the epidermis. It has been associated with D -penicillamine and captopril administration.CLINICAL FEATURES1. Mucosal lesions and erosions are very common. Examination of all mucosal sites is warranted.2. Non-pruritic, painful, flaccid bullae appear that rupture easily. Blisters can be extended or new bullae formed by applying firm tangential pressure on the intact epidermis.3. Weakness, weight loss, and dysphagia may be presenting complaints.DIFFERENTIAL DIAGNOSES— Erythema multiforme— Bullous impetigo— Herpes zosterEVALUATION: Biopsy of lesions shows eosinophils, intraepidermal bullae, and acantholysis. Indirect immunofluorescent staining shows immunoglobulin G antibodies. Serum titers can be followed to evaluate the effectiveness of therapy.THERAPY1. Prednisone (200 to 350 mg/day) for 5 to 10 weeks is used until the cessation of new blister formation occurs. The dosage is then reduced to 40 mg on alternative days and tapered over 1 year.2. Azathioprine (100 mg/day) is added to the regimen and the dosage is reduced over a 4- to 6-month period. Methotrexate and cyclophosphamide can be used instead of azathioprine.3. Topical analgesics (e.g., viscous lidocaine) can be used to alleviate the pain associated with oral lesions.DISPOSITION: Patients with severe cases and oral lesions may require hospital admission for intravenous hydration. Others can be treated as outpatients with close follow-up.

Know about Scorpion Stings
Know about Scorpion Stings
Introduction: A nocturnal arachnid that lives in the Southwest of the United States is the scorpion. It has two venom glands and a stinger in its tail. The majority of species are rather benign, and they often only create a limited reaction similar to that brought on by a bee sting. The bark scorpion (Centruroides sculpturatus) venom, on the other hand, has neurotoxic that can result in a serious reaction. This dangerous scorpion is found on trees in Arizona and New Mexico.CLINICAL FEATURES1. Local effects: The C. sculpturatus scorpion bite causes immediate, excruciating pain at the stung site, as well as swelling and ultimately, numbness. The area that was hurt is extremely sensitive, and the implicated extremity could become paralyzed.2. Systemic effects: The neurotoxin is strongly cholinergic and can cause excessive salivation, blurred vision, muscular spasms, hypertension, and respiratory difficulties.DIFFERENTIAL DIAGNOSES — Snakebite— A puncture wound or other trauma— Insect or spider bite— Drug intoxicationEVALUATION: Typically, the offending scorpion is seen or assumed by history; if safety allows the scorpion to be brought in, this is best. Due to the wide range of symptoms and quick progression, a thorough history and physical examination are necessary.THERAPY1. Pre-hospital management includes rapid transportation of the patient, application of an ice pack to the sting site, and safe transport of the scorpion for identification. When serious symptoms appear, life-saving procedures should be started.2. ED managementa) Antivenin should be administered in all cases of severe envenomation.b) Ventilatory support may be required, with intubation and oxygen for patients with severe systemic response or anaphylaxis.c) Atropine may be required to counteract the cholinergic effects; the dose is titrated to relieve the cholinergic signs.d) Benzodiazepines may be used for seizures and muscle spasms.DISPOSITION: All victims should be observed for 24 hours, especially children. Symptomatic patients should be transferred to the intensive care unit if symptoms are severe.
